Track mounting structure

ABSTRACT

A track mounting structure includes: a linear motor coil, a linear motor magnet correspondingly provided with the linear motor coil, a first track, and a trolley; wherein, the cross-section of the trolley is U-shape, the internal of the U-shape forms a mounting cavity; the first track is provided inside the mounting cavity, two groups of upper rollers being axis crossing are provided between an upper surface of the first track and an upper surface of the mounting cavity. The disclosure moves the track beneath the linear motor coil, thus increasing the available space, which can be used to increase the size and load of the trolley, so as to achieve the purpose of changing the track form and strengthening the track structure.

TECHNICAL FIELD OF THE DISCLOSURE

The disclosure relates to the field of linear track, in particular to atrack mounting structure.

BACKGROUND OF THE DISCLOSURE

Please refer to FIGS. 1 to 3, a linear motor coil 1 and a first track 3are at the same height, that is, in the same plane. When working, thelinear motor coil 1 produces magnetic pole changes so as to push thelinear motor magnet 2, and then push the trolley 4 to move. In general,the position relation between the linear motor coil group and the linearmotor magnet group will not be changed, and the position relationbetween the track and linear motor coil group is changed so that varioustrack designs can be use. However, with this structure, it will be verydifficult and increase the volume a lot if you need to use linear railsor increase the load capacity of the trolley.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to make the purpose, technical solution and advantages of thedisclosure more clearly, the disclosure, combined with drawings andembodiments, will be further detailed. It should be understood that thespecific embodiments described herein are intended only to explain thedisclosure and are not intended to qualify the disclosure.

Please refer to FIGS. 4-6, as one aspect of the disclosure, it providesa track mounting structure including: a linear motor coil 1, a linearmotor magnet 2 correspondingly provided with the linear motor coil 1, afirst track 3, and a trolley 4. The cross-section of the trolley 4 isU-shape, the internal of the U-shape forms a mounting cavity 5. Thefirst track 3 is provided inside the mounting cavity 5, two groups ofupper rollers 6 being axis crossing are provided between an uppersurface of the first track 3 and an upper surface of the mounting cavity5. Two groups of lower rollers 7 being axis crossing are providedbetween a lower surface of the first track 3 and a lower surface of themounting cavity 5. The upper roller 6 and the lower roller 7 arepivotally connected with the trolley 4, and the upper surface of thefirst track 3 is provided with an upper sliding groove 8 with V-shape,the lower surface of the first track 3 is provided with a sliding groove9 with V-shape. The left and right side walls of the two groups of upperrollers 6 are correspondingly provided with the left and right sidewalls of the two groups of the upper sliding groove 8, the linear motormagnet 2 is provided on the trolley 4, the first track 3 is locatedbelow the linear motor coil 1.

Preferably, the trolley 4 is provided with a position sensor 12.Preferably, the trolley 4 is provided with a load 13.

Preferably, the track mounting structure includes an auxiliary wheel 10and a second track 11, the auxiliary wheel 10 can be pivotally providedon one side of the trolley 4, and the auxiliary wheel 10 is movablysupported on the second track 11. Further, the use of auxiliary wheels10 and second track 11 allows to increase load capacity.

When the linear motor coil 1 is powered on, a magnetic force isgenerated to push the linear motor magnet 2 through the change of themagnetic pole. Because the pushing direction is the same as theallowable moving direction of the first track 3, the upper wheel 6, andthe lower roller 7, so the trolley 4 will always move along the firsttrack 3.

In the above-mentioned technical solution, the disclosure moves thetrack beneath the linear motor coil, thus increasing the availablespace, which can be used to increase the size and load of the trolley,so as to achieve the purpose of changing the track form andstrengthening the track structure.

The disclosure splits the linear motor coil 1 from the first track 3 soas to achieve a more flexible structure. When the structure of thedisclosure is adopted, it can be more flexible to freely choose themounting mode of the first track under the condition that the relativeposition of the linear motor coil 1 and the first track 3 is maintained,for example, the first track may be located above, below, or at theright end face of the platform 4, etc.

The embodiments described above represent only a few embodiments of thedisclosure, its description is more specific and detailed, but cannot beunderstood as a limitation on the scope of the patent of the disclosure.It should be pointed out that for ordinary technical personnel in theart, without departing from the concept of the disclosure, you can alsomake a number of deformations and improvements, these are the scope ofprotection of the disclosure.
